Towards evidence based emergency medicine: best BETs from the Manchester Royal Infirmary. BET 2: Incidence of venous thromboembolism in critically injured children.

A short cut review was carried out to establish the incidence of thrombembolic events in traumatically injured children. 75 papers were found using the reported search, of which 5 represent the best evidence to answer the clinical question. The author, date and country of publication, patient group studied, study type, relevant outcomes, results and study weaknesses of these best papers are tabulated. The clinical bottom line is that the risk of VTE events in children is small. Risk factors for VTE can identify a high risk group.
